SPINA is software for determining constant structure-parameters of endocrine feedback control systems from hormone levels obtained in vivo. The first version of this cybernetic approach allows for evaluating the functional status of the thyroid gland, i.e. thyroid's secretory capacity (GT) and sum activity of peripheral deiodinases (GD).

FreeSHIM is an electronic medical device interface that aims to allow any EMR/PM system to talk to any medical device attached to a workstation without having to install tons of pesky drivers or “reinvent the wheel” for each additional device manufacturer.

FreeDiams is a program for making prescriptions of pharmaceutical drugs and testing their interactions. It is the result of building the FreeMedForms prescriber plugins into a standalone application. It is developed by medical doctors and is intended for use by these same professionals. It can be used to prescribe drugs and test drug interactions within a prescription. It can be linked to any application by way of its command line parameters. FreeDiams can use several drug databases, including the FDA_USA drug database, the French AFSSAPS drug database, the Canadian drug databases, and the South African drug database (SAEPI).

pydicom is a pure Python package for working with DICOM files, the standard for medical images and related information. It allows you to inspect and modify DICOM data in an easy "Pythonic" way. The modifications can be written to a new file.

ESP is a secure, automated system that analyzes
electronic medical record (EMR) data to identify
and report patients with notifiable diseases to
the Massachusetts Department of Public Health.
The growing use of electronic medical record
systems (EMRs) permits efficient re-use of data
already being collected by clinicians during
routine private practice, offering an unparalleled
opportunity to improve public health practice.
Information held in EMR systems includes
diagnoses, procedures, laboratory test, and
treatment information, as well as patient
demographic data. This software permits secure,
simple, and robust messaging from electronic
medical record systems to public health authorities.

Mathnetics is an API for creating advanced,
interactive, Web-based mathematical applications.
It defines various important mathematical objects
that are inter-related and on which many numerical
calculations can be done. It also features
rendering of 3D objects onto an SVG canvas (to do
so, it includes certain utilities such as browser
sniffing, DOM node selection, and DOM readiness
detection), which is quite robust. A few basic 3D
objects are given (Line, Sphere, Cube), but the
user can define any 3D object desired as per the
specification.

The Bio2RDF software is a package which resolves
bio2rdf.org semantic Web identifiers corresponding
to bioinformatics data and knowledge bases into
RDF files which can be consumed by any generic RDF
processor.

French AGGIR Calculator is a very small
application that calculates the AGGIR score, a
medical score that classifies patients into six
different degrees of dependence. It is used by
doctors and the French administration. You can use
this application on the command line, integrate
the source into your own project. It is written in
pure C/C++ and is cross-compilable.

AMIDE (Amide's a Medical Imaging Data Examiner) is
a tool for viewing, analyzing, and registering
volumetric medical imaging data sets. It's been
written on top of GTK+, and runs on any system
that supports this toolkit (Linux, Windows, Mac OS
X with fink, etc.).
